Does anyone know what documents my parents that live in Portugal would need to visit Canada as tourists for a few days?
Is a Passport required and do they need to get anything else?

They need a valid passport and a roundtrip ticket. As well as a ETA https://www.canada.ca/en/immigration-re ... mpaign=eta

Hubby is Portuegese and we have have family come visit us often (emphasis on the roundtrip ticket- some family members are given a hard time).
